Rezumat

In the article, there are presented results of morphological and histochemical researches of embryogenesis after direct and indirect experimental pollinations of all dichogamous types (homogamous, protandrous, protoginous) of walnut (Juglans regia L). It has been established that the tardiest period of passage of all developmental stages was noticed at protandrous genotypes after free pollination. According to the histochemical tests, the most intensive metabolism was observed at the stage of globular embryo of all dichogamous studied types not depending on the type of experimental pollination. Experimental heitonogamy provoke more rapid embriogenetic processes within all dichogamous types.
